I really like this game and have done over a 1000 stages, so now I almost always use the extra tube feature to pass the levels, since these stages are quite challenging, but it's still a fun puzzle experience and a nice way to distract the mind. My only issue is with the recent update, which allows you to pick multiple balls at the same time, it might be helpful for other players, but I would prefer if it was an optional feature, since I'm already used to moving one ball at a time 😅
